What it does

MCP Installer is an agent skill from lintendo/Axhub-Skills. Install and configure MCP servers across desktop and CLI clients (Claude, Cline, Windsurf, Cursor, VSCode, Gemini CLI, Codex, Trae, Antigravity, etc.) on macOS/Windows/Linux, preferring @smithery/cli when supported and otherwise performing manual JSON config updates and path discovery.

Its SKILL.md is about 780 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/clients.md`).

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol, macOS, Visual Studio Code and Linux. The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit 1e1c5bc. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

MCP Installer loads about 778 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 75 tokens; SKILL.md has 353 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~75
When it runs · the whole SKILL.md, loaded when a task matches: ~778
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

MCP Installer

Overview

Install MCP server configurations across multiple clients and OSes with a CLI-first workflow and a safe manual fallback.

Workflow

1) Collect inputs

Identify the target client ID and OS; use references/clients.md for the supported list and known paths.
Gather MCP server definitions (name -> config object) and decide whether to override existing entries.
If any provided MCP config includes secrets (for example fields like key, token, apiKey, accessToken, secret, password, or Authorization, or env vars like *_KEY, *_TOKEN), pause the install and ask the user to obtain/provide those values first. Only proceed once the user confirms they have the required credentials (or requests installing a placeholder and will fill it in later).

2) Prefer @smithery/cli (when supported)

Run npx @smithery/cli --help and npx @smithery/cli install --help to confirm the exact syntax.
Use the CLI install flow for the client ID; if the CLI rejects the client or fails, fall back to manual edits.

3) Manual install (JSON config fallback)

Locate the config file path (see references/clients.md). If unknown, search standard config dirs for files like mcp.json, mcp_config.json, claude_desktop_config.json, or cline_mcp_settings.json.
Read existing JSON and ensure a top-level mcpServers object exists.
Merge servers: add new names; replace existing when override is true; preserve all other keys.
Write JSON with 2-space indentation.

Example shape:

json

{
  "mcpServers": {
    "example-server": {
      "command": "npx",
      "args": ["-y", "example-mcp@latest"],
      "env": {}
    }
  }
}

Show full SKILL.md (139 more words)Show less

4) Verify and troubleshoot

Restart the client and confirm the MCP servers appear.
If writes fail on macOS, prompt for Full Disk Access and ensure the client app is closed before writing.
For CLI-only clients (for example claude-code), use the client CLI help to locate its MCP install/config command.
If Trae/Trae-CN installs fail due to permissions or other errors, generate a deep link and return it as a fallback.

5) Trae deep-link fallback

If trae or trae-cn cannot write to disk, generate a schema link for the user to open in Trae:

trae: trae://trae.ai-ide/mcp-import?type=${TYPE}&name=${NAME}&config=${BASE64_ENCODED_CONFIG}
trae-cn: trae-cn://trae.ai-ide/mcp-import?type=${TYPE}&name=${NAME}&config=${BASE64_ENCODED_CONFIG}

Rules:

TYPE is the MCP transport type (for example streamable-http).
NAME is the server name shown in Trae.
config is the base64-encoded JSON config object for that server (no whitespace, UTF-8 bytes).

References

Use references/clients.md for client IDs, aliases, and known config paths.
